The drug removes from the brain the amyloid proteins that are believed to cause Alzheimer’s. The plaques can show up in people with very mild memory problems, Jicha said; one of three Americans over age 65 have them.
The study continues, to see if the drug can be used to remove plaques earlier and delay onset of teh disease, Jicha said. “Hopefully we’ll have that answer in the next five to seven years.”
UK is still recruiting participants for the study. It uses a simple blood test for the protein or likelihood of buildup. If there is a high likelihood, imaging of the brain can see the plaques may be performed. If they are found, the person gets into the study. But only half of them get the drug; the others get a placebo, which is standard for clinical trials. They could get the drug if the study is successful, Jicha said.
